Populate a component mask with all the necessary mutually inclusive components given an input type. Mutual components that already existed in InMask will not be added or counted. Can be used to populate a new mask with only the mutual components, or to add the components to an existing mask.
The number of new components added to OutMask. Only components that did not exist before are considered.
